Amount: 20 percent soluble powder in drinking water. Administer at the 0.012 percent level in drinking water as soon as coccidiosis is diagnosed and continue for from 3 to 5 days (in severe outbreaks, give amprolium at the 0.024 percent level). Continue with 0.006 percent amprolium-medicated water for an additional 1 to 2 weeks.

Indications: Treatment of coccidiosis.

Limitations: No other source of drinking water should be available to the birds during this time. As sole source of amprolium.

Turkeys

Amount: 20 percent soluble powder in drinking water. Administer at the 0.012 percent level in drinking water as soon as coccidiosis is diagnosed and continue for from 3 to 5 days (in severe outbreaks, give amprolium at the 0.024 percent level). Continue with 0.006 percent amprolium-medicated water for an additional 1 to 2 weeks.

Indications: Treatment of coccidiosis.

Limitations: No other source of drinking water should be available to the birds during this time. As sole source of amprolium.

Cattle (calves)

Amount: 20 percent soluble powder in drinking water.

Indications: As an aid in the treatment of coccidiosis caused by Eimeria bovis and E. zurnii. in calves.

Limitations: Add 4 ounces of the soluble powder to each 50 gallons of drinking water. At the usual rate of water consumption, this will provide an intake of approximately 10 milligrams per kilogram (2.2 pounds) of body weight. Offer this solution as the only source of water for 5 days. For a satisfactory diagnosis, a microscopic examination of the feces should be done by a veterinarian or diagnostic laboratory before treatment. When treating outbreaks, the drug should be administered promptly after diagnosis is determined. Withdraw 24 hours before slaughter. A withdrawal period has not been established for this product in pre-ruminating calves. Do not use in calves to be processed for veal.
